[Epic 4G General] mkasick:
To be honest, I doubt it's a decision that Samsung spend much time on in the first place.

RFS is part of their proprietary off-the-shelf storage stack, and I doubt there was much testing to determine if, performance wise, RFS was a good match for Android or the underlying hardware. Simliar to how many of their other software drivers are unoptimized, like the keyboard, sound, etc.

That said, going with RFS was not an unreasonble choice on their part. Keep in mind the decision (at least for Galaxy S devices) was made for Eclair which ran Linux 2.6.29, in which ext4 was much more a "work in progress" than 2.6.32 or later.

As for RFS vs ext4, there's a few other factors to keep in mind:

First, while FAT is a simple filesystem relative to ext[234], it's less featureful in some important ways. For one, block indexes are stored in a linked list, instead of block maps or extents. While that's fine for sequential access, it's bad for intrafile random access, of which unfortunately, Android makes a good amount of use of by mmaping .apks into the process address space to provide access to program assets.

Second, in addition to benefits on the underlying file system structure, the ext4 driver has lots of peformance tweaks over years of focus on improving responsiveness to desktop workloads. I would assume, especially based on observed performance, that RFS is a more naive implementation, or at least tuned for "robustness" (data consistency) over performance.

In short, ext4 is the obvious file system choice for anyone building a phone today with an underlying MMC controller, and that's why its used in the Nexus S and SGSII. Meanwhile, for devices that already run RFS, the switch to ext4 is compelled by the degree to which RFS underperforms, which is less on the Epic than other devices.

As for "no journal', it's dangerous outside /cache and has been known to be a bad idea for a long time.
[Epic 4G General] JohnCorleone:
Wow, thanks mkasick. That was the kind of explanation I was asking for.
[Epic 4G General] JohnCorleone:
Ok mattallica, can you explain this in a little more detail please? That's the one thing that irks me too. This thread is getting better with each post. I have some "thanks" to dish out for the free education I got.
[Epic 4G General] mattallica76:
Sure. If you have a folder with a large number of media files on your SD that you want the media scanner to skip (not scan), create a file in that directory named

.nomedia

You might have trouble doing this in windows, so you might want to use a file browser like ES or Root Explorer.
[Epic 4G General] JohnCorleone:
Ok, many thanks for that info. I also was wondering if developers are already implementing SD speed tweaks into ROMs. Are apps like SD Speed Increase actually beneficial? If so, what is the optimal setting here? I have noticed that some ROMs do read the SD card faster natively so I figured that some sort of tweak must be baked in. In those instances would the app do more harm than good? Sorry for all of the questions but since all of the questions I have had seem to be getting answered here, I might as well get my last few out.
[Epic 4G General] libracolo:
I agree with you (on the cache cleaning). As a manager of a software testing group (Windows based), I can say that it is standard practice for me to delete the "temp" folders after installing a new OS, un-installing an app, etc. I can't tell you the number of people who have found "bugs" with apps that had more to do with the amount of junk built up in their temp folders, than the app itself. I don't claim to be a Linux expert, but I know alot of the software I deal with involves extracting files (during an install) or writing certain "user" files (while installed) that don't get cleaned up, no matter how good the un-install is. To me, it's a matter of habit to clean up certain folders/files as a matter of course before even starting a new testing project (to ensure a clean environment). Wouldn't the same concept apply on the ROM side? Just my 2 cents worth.
[Epic 4G General] JohnCorleone:
It absolutely seems to be the case. I keep nandroids of several different ROMs that are all set the way I like them but when I test something its always on a clean install. I can probably run Odin with my eyes closed at this point
[Epic 4G General] chris41g:
you can, in adb or a terminal app goto any directory and type "touch .nomedia"

and that will cause media scanner not to scan that directory. but i do not recomend doing on the ringtone or notification tone directories on /system for gb.. if so you wont have any..

[XPERIA X10 Q&A, Help & Troubleshooting] KeizBaby:
If I'm right the standard music player for Android is the one you get with the ROM only it is modified by SE. Maybe you can grab the music player from an AOSP Gingerbread ROM.

Can you rename a Nandroid backup? With so many ROM's out there, I want to try different ones but there is no way I will remember which backup is what unless I can rename them.
[HTC EVO 3D] Excrucibo:
The short answer seems to be: yes. I'm only Googling this, so I can't verify.
[HTC EVO 3D] spencer88:
I believe you can rename any backup, just don't put spaces in the backup name.

I've renamed backups with Amon RA recovery on the OG EVO and now with ClockworkMod 4.0.1.4 on the EVO 3D.

Creating and restoring those backups went flawlessly.
[HTC EVO 3D] mrrogers1:
Yes, you can rename it to whatever you like since you are going to manually select the file anyhow. The system won't balk at your renaming of the file. Keeping spaces out is always good, seen problems with this is in the past.

You should root your device and then use SystemApp Remover to uninstall them.

Is there something specific to the platform that is preventing enhanced .m4a support on Android? As far as I can see from scouring the internet, it looks like we don't have a single media player that supports the enhanced features of chaptering and embedded images offered by enhanced .m4a files. This is supported in every apple device, if I am not mistaken.

Any ideas?

I'm desperately searching for one, but I've had no luck.
[General Questions and Answers] delboydell:
has anyone had any luck yet with this one? I am thinking about using my old hd2 just for m4a playback
[General Questions and Answers] Hurtcake:
I asked the developer of Pocketcasts about this. And it seems they're missing the tools to make this.

" We've been looking into it, but that format is a proprietary Apple standard that no one else has support for. So our iOS app supports it out of the box, because Apple has the developer tools for us to do that. On Android Google don't, and we've yet to find a third-party library we can use that does, which leaves us stuck. So short story: yes we'd love to, but we don't think we can."

Bummer.
[General Questions and Answers] geoken:
The feature is supported by VLC on the desktop (and likely other open source desktop apps). Handbrake also supports it; it can encode the chapter data into m4v files. In reading about it, it seems like the chapter data is simply encoded into the file in plaintext. I don't know how easy or hard it is to read that data on Android, but it definitely seems do-able (seeing as how the above 2 open source apps do it).
